New Brake Rotors??
Okay, 08 automatic, 80k miles. Just wanting to confirm this. I got new brake pads on front and back of my car, ceramic kind. My front rotors are warped, got them checked and they don't meet minimum spec, so I have to get new ones. Not mechanically inclined so I have to take it to a shop. What SHOULD be a reasonable price range to buy and install? 350$? 250? Just wanting to check, and also, to make sure it is the rotors, it sounds like grinding or metal rather than a high squeal( bad or cheap pads) can that noise be the cause of bad rotors. Thank you.
Going to get them in 3-4 days.

Live with the new brakes for awhile. They take time to wear in.

Anything over $150 is price gouging. Grinding is just probably pads. Warped rotors you would feel thru the brake pedal as a pulsating sensation; sorta an on-off-again braking. The pedal would most probably modulate against your foot as you are braking.

It can take several hundred miles for new pads to wear in.
The pulsations you feel in the brake pedal can be caused by things other than warped rotors. Perhaps the mechanic who changed your pads got his greasy fingerprints all over both sides of the rotors.
Try this: find yourself an empty back road somewhere. Accelerate from a standing start to at least 60 mph and hit the brakes hard till you come to a complete stop. Accelerate in reverse to 6,000 rpm and hit the brakes hard. Repeat the above at least a half-dozen times with hardly a pause between.
If that doesn't improve the situation then you MAY have warped rotors, although warped rotors on a street driven RX8 is pretty unlikely. I have 86K miles on the original rotors and they are still in decent shape. I don't track, but I do drive VERY aggressively.
On reflection though if you feel strongly that you need new rotors go ahead and have them replaced. With 80K miles on 'em it certainly ain't gonna hurt nuthin'.
